Group-relative Trajectory-based Policy Optimization: Increasing Quality and Training Stability

OpenMedRL is an open-source reinforcement learning environment for benchmarking LLM-powered medical agents in emergency care. It simulates triage, dynamic patient progression, resource constraints, and uncertainty-aware clinical decision-making.

RL training environments with verifiable rewards for coding agents. Works with TRL, Unsloth, verl, OpenRLHF.

An OpenEnv RL environment where an LLM agent plays the buyer and negotiates against an LLM-powered seller over real marketplace listings.

This repository contains my personal notes and hands-on implementations for fine-tuning and post-training Large Language Models (LLMs).

Low-cost GRPO fine-tuning pipeline for valence-arousal state estimation and tone-aligned responses in Llama 3.2 1B.

A reinforcement learning fine-tuned model that generates Linux terminal commands from natural language descriptions. Trained using GRPO (Group Relative Policy Optimization) on a custom terminal task environment inspired by CAMEL-AI's SETA framework.
